Speaking of the Emerson CQC-x knives... Kershaw makes a couple of Emerson knives for very little money.
They are decent knives and you can get them for around $45 shipped. Sure they are not a $200+ knife but they serve a purpose, I have the CQC-4kXL which has a nearly 4" blade and is very intimidating to look at, it would be a great defensive knife and is cheap enough to use for everyday tasks like working on the car and whatnot.
They are very easy to disassemble so you can "clean it up" meaning file off any burrs and generally slick it up, even though out of the box they are still nice and good to go.
I got one for my wife to carry when she walks the dogs. The quick opening "wave" technology is pretty cool. (Check the link below for a video on how the wave thing works)
Heck even my son, the knife snob who sneers at anything less than a $300 knife, had to admit for $45 the Kershaw Emerson was a pretty good deal, he said he wanted to get one so he could use it without fear of breaking or loosing it like one of his $300-$400 fancy knives.
This is the one I have:
